• SP AF 17-50mm F/2.8 XR Di II VC

Stabilized. Fast. Super Performance.

The large-aperture and excellent optical performance that this lens offers is ideal for low-light photography and enriched creative picture composition possibilities. The new lens delivers pin sharp results and remarkable contrasts throughout the entire focal length range. With an aperture of F/2.8 impressive photos with smooth, even bokeh (background blur), can be shot helping to emphasize subjects by means of a very shallow depth of field.

This lens is equipped with a tri-axial image stabilizer called vibration Compensation (VC), a Tamron proprietary development. The VC feature minimizes the effects of camera vibrations and shake of hand-held photography. The lens offers more photographic possibilities for shots at longer shutter speeds, making it ideally suitable for "Available Light" photography in low-light conditions.

Delivering leading-edge image quality

The optical design of this lens uses a high-performance XLD (Extra Low Dispersion) element, which is manufactured out of a special glass with an extremely low refractive index. The refractive index describes the ability of the lens to split a light beam into its spectral colours. The dispersive properties are even lower than standard LD lenses and are at a level similar to fluorite. The XLD lens in combination with the LD element delivers the highest contrast and brilliance. This effectively prevents the problem of chromatic aberration in telephoto photography and delivers a high level of sharpness even in the peripheral regions. The result is a lens that effectively compensates for axial chromatic aberration and magnification aberration throughout the entire zoom range and guarantees the highest resolution and brilliance for your pictures.

VC Image Stabilization (Vibration Compensation)

The tried-and-tested Tamron VC Image Stabilizer (Vibration Compensation) ensures this lens delivers sharp and shake-free images. This means that the lens is also perfectly suited for hand-held photos and low-light conditions.
